TL;DR: In this paper, the formfactors and overlaps for light and heavy ion transfer reactions are evaluated including finite range and recoil effects, and the treatment of the recoil is based on a separation into a transversal effect, responsible for a modification of the selection rules, and a longitudinal effect related to a scaling of the radial motion.

TL;DR: In this paper, the basic theoretical concepts involved in the interpretation of spectroscopic data for the range from the ultraviolet to the X-ray region are outlined and a short account is given of the experimental aspects of work with synchrotron radiation.

TL;DR: In this paper, radiofrequency spectroscopy has been extended to positive ions with S ground states by means of optical pumping, where the ions are stored in buffer gases or ion traps and are polarized directly by optical pumping or indirectly by spin exchange, change exchange, or penning ionization with optically pumped atoms.

TL;DR: In this paper, the semi-classical (WKB) approximation in three dimensions is considered for scattering processes, which represent contributions to the quantal wave in classically forbidden regions, and in particular describe diffractive effects in the cases where the scattering potential varies appreciably within a wavelength.

TL;DR: In this article, a pedagogic review is presented, for the benefit of the non-particle physicist, of recent remarkable conclusions drawn from the ft values of various superallowed nuclear decays, which are known to great accuracy - such accuracy, in fact, that radiative corrections have to be taken into account to compare the theory with experiment.
